Users whose accounts are no longer eligible to be in the chat room will be
disconnected immediately from chat when their account status changes.
The places in nonshy where these disconnects may happen include:
* When the user deactivates or deletes their account.
* When they modify their settings to mark their profile as 'private,' making
them become a Shy Account.
* When they edit or delete their photos in case they have moved their final
public photo to be private, making them become a Shy Account.
* When the user deletes their certification photo, or uploads a new cert photo
to be reviewed (in both cases, losing account certified status).
* When an admin user rejects their certification photo, even retroactively.
* On admin actions against a user, including: banning them, deleting their
user account.
Other changes made include:
* When signing up an account and e-mail sending is not enabled (e.g. local
dev environment), the SignupToken is still created and logged to the console
so you can continue the signup manually.
* On the new account DOB prompt, add a link to manually input their birthdate
as text similar to on the Age Gate page.
* Signup: if entering an existing email, don't admit that the email
exists. Instead, send a specialized email to its address.
* Search: no longer search for users by email address.
* Login: always hash the incoming password on user not found, to take
constant time compared to when the user did exist.
* Fix a pagination bug when a private (shy account) views a non-friend's
photo gallery.
